Abstract
DC60 (04/08/57) การประดิษฐ์นี้เกี่ยวกับ การใช้ของสารละลายที่มี กลูแทมิคแอซิด N,N- ไดแอซีติกแอซิด หรือ เกลือของสารเหล่านี้ (GLDA) และ/หรือ เมธิลไกลซีน N,N-ไดแอซีติกแอซิด หรือเกลือของสาร เหล่านั้น (MGDA) ในการจัดการ ชั้นกักเก็บใต้ดิน, ซึ่ง สารละลายเหล่านั้น สัมผัส บริภัณฑ์ที่มี เหล็กกล้าคาร์บอน, และเกี่ยวกับระบบที่มีวัสดุที่มีเหล็กกล้าคาร์บอน สัมผัสกับ สารละลายที่มี กลูแทมิคแอซิด N,N-ไดแอซีติกแอซิด หรือเกลือของสารเหล่านั้น (GLDA) และ/หรือ เมธิลไกลซีน N,N-ไดแอซีติกแอซิด หรือเกลือของสารเหล่านั้น (MGDA), ที่อุณหภูมิที่ยกสูง และ/หรือ การใช้ ประเภทเหล็กกล้าคาร์บอน ตามที่พบโดยปรกติในชั้นกักเก็บใต้ดิน DC60 (04/08/57) This invention is about Use of a solution containing Glutamic acid N, N-diacetic acid or salt of these substances (GLDA) and / or methyl glycine N, N-diacetic acid. Or their salts (MGDA) in underground storage management, where they come into contact with equipment containing Carbon steel, and on systems with carbon steel-containing materials in contact with solutions containing Glutamic Acid N, N-diacetic acid Or salts of those substances (GLDA) and / or methyl glycine N, N-diacetic acid Or their salts (MGDA), at elevated temperatures and / or the use of carbon steel As is commonly found in underground containment layers
